TMM may fail to achieve ready-for-world status (as shown in the HA Status table) due to a number of possible reasons. Currently, there is no direct logging of the specific reason that TMM fails to achieve ready-for-world status.
Diagnosing situations where TMM does not become Ready-For-World requires understanding the requirements/dependencies for TMM to become Ready-For-World, and examining indirect logged data to confirm which dependency failed in each observed case.
TMM ready-for-world condition (as shown in the HA Status table) fails, and the HA group member fails to become active and to begin passing traffic.
None
The tmm/ready_for_world_stat tmstat table now list the components upon which TMM depends to become Ready For World, and indicates whether each is currently in a 'ready' versus 'not_ready' state. For example: # tmctl -d blade tmm/ready_for_world_stat name ready not_ready ---- -------------------------------------------------- --------- tmm0 platform_msg,shared_random,cmp_mpi,dag_transition,
